Today is better.  I talked to my boss about why I didn't get the promotion, and the reasons were what I suspected.  He used it as a springboard to turn someone permanent, and, of course, they don't want me off of the queue for any amount of time since I'm too good at what I do.  I guess that's a positive?

I'm still dragging physically and emotionally, but at least there's only one more day to go.
